Final answer:
In a skin assessment, a nurse would consider a lesion suspicious for skin cancer if it is irregular in shape and color with uneven borders, similar to the characteristics of melanomas. Melanomas are typically larger than 0.5 centimeters, can be raised, firm, and show growth.
Step-by-step explanation:
In a skin assessment for skin cancer, a nurse would consider a lesion suspicious if it follows the characteristics of melanoma, the most fatal of all skin cancers. Melanomas generally present as irregular in shape and color with uneven borders (Option 4). They are often large brown or black patches, and are typically larger than 0.5 centimeters in diameter. Melanomas may also be raised on the skin surface, feel firm to the touch, and show signs of growth over time. Finally, they can also change shape, which further adds to their suspicious nature.
